由於剛剛入門android開發，想學習一下APP後端開發，故在網上找了一個demo，除錯一下跑通了，本文章主要記錄，github上down下來的程式碼怎麼調通。

app後臺程式碼：https://github.com/luqinmao/HomeServer

（1）先執行自帶的home.sql檔案，生成對應的資料庫。

（2）修改db.properties檔案，密碼修改成自己的mysql密碼。

（3）修改Tomcat版本，修改java版本。

android程式碼：https://github.com/luqinmao/Home

（1）修改 AppConst.java檔案，將ip地址改成自己的。

（2）將gradle-wrapper.properties檔案改成4.4-all。

（3）將Home目錄下的build.gradle檔案改成3.1.2。

（4）主要修改app目錄下的build.gradle檔案，修改結果如下：

apply plugin: 'com.android.application'

android {
    signingConfigs {
        config {
        }
        config1 {
            keyAlias 'home'
 
            keyPassword '123456'
            storeFile file('/home/gs/01_android/signed/home.jks')
            storePassword '123456'
        }
    }

        }
    }

        release {
            minifyEnabled false

            signingConfig signingConfigs.config1
        }
        debug {
            signingConfig signingConfigs.config1
        }
    }

        main {
            jniLibs.srcDirs = ['libs']
        }
    }
